Abstract

The present invention is a method to provide fault tolerant and dual redundant navigation data to flight management system and Radar functionalities of an Aircraft. The present method, main INGPS (Inertial Navigation and Global Positioning System) of the aircraft and Radar-INGPS (INGPS of the on-board Radar) are integrated with avionics computer to achieve failure management and dual redundancy in navigation data. The avionics computer synchronizes both the INGPS and the Radar computer with itself with same clock for synchronized operation and data correlation. Avionics computer continuously monitor the failure status of both the main INGPS and Radar-INGPS. It utilizes navigation data from the main INGPS for the flight management and other mission functionalities if no failure in main INGPS. It provides navigation data from Radar INGPS to Radar computer, if no failure in the Radar-INGPS. If avionics computer detects failure in Inertial Navigation System of the main INGPS, it uses navigation data from Radar INGPS for flight management and avionics computations and maintains full capabilities of the aircraft avionics without any performance degradation. The avionics computer detects failure in Radar INGPS; it provides navigation data from main INGPS to Radar computer to enable Radar operation without any degradation. The method also facilitates pilot to select navigation data from Radar INGPS for flight management and avionics computations even if the main INGPS is not failed, through Cockpit Control Panel of the aircraft.
